"Ultra-high barrier films for r2r encapsulation of flexible electronics" (FLEXONICS)

STREP Project (2005 - 2008)
Coordination by LTFN
Project Coordinator : Prof. S. Logothetidis

Flexible electronic devices (FEDs) will have a major impact in our daily life if they will be encapsulated into transparent, ultra-high barrier, flexible materials, providing protection against oxygen and vapor, long-term stability and endurance. The realization of such materials, compatible with roll-to-roll (r2r) production processes will allow cost effective large scale FEDs production.
FLEXONICS is a STREP Project with the goal to develop:

  • materials systems consisting of alternating inorganic/organic layers few nm thick to improve the current barrier properties of flexible films by at least a factor of 1000,
  • the relative r2r processes, which will be used for the production of such materials,
  • optical & real-time techniques for process control and optimization, with final and specific goal the effective encapsulation of flexible OPV and OLED devices.

The above objectives conform to the NMP activity on "Materials processing by radically innovative technologies". The project will extend the knowledge on hybrid organic/inorganic systems, their interfaces and their optical and barrier properties. New techniques will be developed to measure and model the ultra-low gas permeation.
Finally, the optical properties of the hybrid organic/inorganic layers and the light interaction with complex-structured materials will be studied at the fundamental level.
